Astrophysicists have created a three-dimensional model of supernova explosion residues

Astrophysics from the Harvard-Smithsonian Center, based on observations, made up a three-dimensional model of supernova remnants known as Cassiopeia A. This star was located 11000 light years from Earth. The light of the explosion was supposed to reach us about 340 years ago, however, for some reason this phenomenon was not recorded in history. Now the remains of the star are a giant "bubble" with a diameter of about 10 light years.

The former supernovae is perhaps one of the most studied objects of its kind, but at the same time it still keeps some riddles that remain undiscovered despite all computer simulations. A three-dimensional model built using observations of the telescope of the Kitt-Peak National Observatory in Arizona will help to actively study the properties of this interesting object.

Den Milisavlevich, the leader of the team researcher, says : “We are doing about the same thing as the experts in bomb explosions. We investigate the remnants of the explosion in order to understand what has exploded and how. Our work is a big step forward in understanding the processes of the explosion of stars. ”

By the end of life, the stars lose their symmetry and take an irregular shape, as a result of which the explosion remains asymmetric and have areas filled with matter and massive voids.
